In the access database the date field is of datetime type. The dates are in european DD.MM.YYYY format which i transform using datetime variable and convert function. The sql query runs fine in access database but when i run it thru my oledb connection in my asp.net page it gives me errors. How should i modify my query, or make adjustments to my code, to not get this error? Do i need to send the datetime as a parameter? And how do i do that? Here is the code for the search event:

I am importing data from an Excel worksheet. The columns are labelled aa, ab, ac .... in row1 and the rows are labelled with integers in col aa. Although I can import the entire worksheet (so long as it isn't too big), when I add a WHERE clause to import only a single row I get a type mismatch which I have not been able to isolate. How can I make progress.

I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names. So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
I am using C# windows based GUI and MS-Access as my database. Unfortunately, I cannot insert a record with a numeric value, this means that one of my field is a number data type. Below is my code;
Code:
strItemCode = lvProducts.Items[i].SubItems[0].Text.Trim();
iQty = int.Parse(lvProducts.Items[i].SubItems[2].Text);
cmAdjustedItems.CommandText = "INSERT INTO tblAdjustedItems VALUES(@itemcode, @adjustmentid, @qty)";
cmAdjustedItems.Parameters.AddWithValue("@itemcode", strItemCode);
cmAdjustedItems.Parameters.AddWithValue("@adjustmentid", strAdjustmentID);
cmAdjustedItems.Parameters.AddWithValue("@qty", iQty);
cmAdjustedItems.ExecuteNonQuery();
All the variables in my code were properly declared.
im using MS-Access database, i tried to add some data to the database from C#. the column datatype is Memo.

I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?

I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:
"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
...or
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."
